Ceramic Ball (also called as Inert Alumina Ball), with the characters of high mechanical strength, high chemical stability, and excellent heat endurance, inert alumina ball can resist high temperature, high pressure, acid, alkali, salt and various organic solvents.

As the material to support and cover catalyst in the reactor, inert alumina ball can buffer gas or liquid's flush on catalyst so as to protect catalyst. It also can improve distribution of gas or liquid in the reactor.

Therefore, it's widely applied in petrochemical, chemical, fertilizer, gas and environmental protection industries.
